I COMBINED DUMP AND ELEVATOR.

Specification of Letters Patent.

Application filed February 5, 1913. Serial NO. 7%,318.

Be it known that I, ALEREDF. MEYER, a citizen of the United States, resldingat Morton, in the county of Tazewell and State of Illinois, have invented certain-new and useful Improvements in Combined Dumps and Elevators, of which the following is a specification. V

My invention relates to improvements in combined dump and elevators andparticularly to the driving mechanism therefor.

The principal object of my invention is the provision of a driving mechanism for a com bined dump and elevator so arranged that the source of power is located on the side of the elevator opposite the dumpand hav ing connections whereby the elevator and dump may be separately clutched in driving relation to said source of power, as deslred, but whereby the dump and elevator may not be simultaneously connected with the source of power. A I

To the accomplishment of the foregoing and such other objects as may hereinafter appear my invention consists'in the construction, combination and arrangement of parts hereinafter described and then sought to be defined in the appended claims reference being had to the accompanying drawings forming a part hereof and which show for the purposes of illustrative disclosure, two embodiments of my invention, it being expressly understood that minor changes may be made within the scope of theclaims without digressing from my inventive idea.

In the drawings:, Figure 1 represents a digrammatic' view showing, in elevation, part of a power device, part of a .dumpwith an elevator located therebetweemtheoperative connections being constructed according to my invention; Fig. 2 is a front elevation of the lower portion of the elevator shown in Fig. 1 showing the operative connections; Fig. 3 represents a side elevation of the lower portion of the elevator and con-' nections, looking at the right hand side of Fig. 2; Fig. 1 is a viewsimilar to Fig. 3, showing asliglitlydiiferent driving connection for the elevator, and, Figaois a vertical vator.

the source of power but never simultaneously. These connections include a shaft for operating the dump and a clutch device for operatively connecting it to the driving shaft from the source of power. This driving shaft has a sprocket loosely mounted thereon having a connection to drive the elevating mechanism, the, same clutch device being adapted to operatively connect the sprocket to the driving shaft. Said clutch device is so arranged that when the dump is operatively connected to the driving shaft, the elevator will not be connected, and vice versa.

Referring now to the drawings, the numeral l designates the source of power which is illustrated as being in the form of a con.- ventional type of horse power itbeingunderstood however that I may utilize any desirable source Of power or motor. The driving shaft 2 is operatedby the motor 1, having the universal joints 3 connecting it to the shaft at extending through the boot 5 of elevator 6. The construction of, this elevator is not shown in detail as it maybe of any type, portable or permanent, or built for exterior or interior use. In the form shown it includes the boot 5, vertical leg portions 7 having the conveyer chains 8 with the buckets 9 thereon running therein. The chains 8 run over sprockets 10 on shaft 11 at the upper end of the leg of the elevator and over sprockets 12 which are loosely mounted on shaft 4 in the boot of the ele- Shaft llis driven by means of the sprocket chain 13 engaging the sprocket wheel 14 on its outer end, said chain also running Over sprocket wheel 15 which is loosely mounted on shaft 4 outside of the boot of the elevator and is adapted to be clutched to said shaft by the operator. The

sprocket wheel 16 is provided to operate a conveyer'in drag 17, which is only partially shown.

The shaft 4 is suitably supported in bearings in the sides of the boot of the elevator, its .end terminating in juxtaposition and alinement with the dump driving shaft 18 which is supported by the bracket member 19 and is adapted to, drive the dump 20,

parts of which only are shown, as the details thereof do not constitute features of this invention, which may be used with any form of dump,

As a means of connecting either the ele- 11o 'vator or dump mechanism in operative rela- 1 tion with the power, I provide the form of clutch construction shown in Fig. l and in As stated enlarged detail in'Figs. 2 and 5. hereinbefore, sprocket wheel is. loosely mounted onshaft 1 and further is provided with the hub portion 21 having the clutch face 22. The dump driving shaft 18 has 7 tends over the end portions of both shafts.

fixedly secured thereon the membero'r collar '28 having the clutch face 2 1. The ends of the shafts 4: and 18 are in close proximity so that'the clutching member or sleeveex- This sleeve 25' has the clutch faces 26 corresponding and facing the clutch faces 22 and 24:, and is slidably mounted on shaft tby means of the slot and key connection 27 I As shown in Fig. 5, this key 27 extends against the hub portion 21 of the sprocket wheel 15 .so as tohold said sprocket wheel in its proper position. Thesleeve 25' is grooved as at 28, to receive the yoke member 29' of the operating lever 30, the latter being pivoted to the bracket member 19, as at 31. As

the clutching member or sleeve 25 is keyed: to the shaft t which is always connected to the driving shaft 2 of the motor. .or power 1, it is obvious that its movement in one direction will clutch the sprocket wheel 15 in operative relation to said driving shaft so'as to drive said elevator, and that its movement in the other direction will break said operative connection between the driving shaft and the elevator and. clutch the dump driving shaft 18in operative connection with the driving shaft 2 so as to operate the dump, and vice versa. v I Theconstruction shown in Fig. a is substantially the same, differing in that the driving shaft is mounted outside of theboot,

.the sprocket'wheels 12 being fast on shaft 1' in the boot of the elevator which is driven by means of sprocket wheel 14, sprocket chain 13 and sprocket wheel l5 which is adapted to'be operatively connected to the source'of power in substantially the same.

' manner as sprocket wheel 15, it beingunders'tood that said sprocket wheel 15 is normally loose on the driving shaft. T

v This invention is advantageous for the reason that it may be readily used with motors of small power where the motors cannot operate the dump and elevator simultaneously. It frequently happens that the motor of the operator has not the power for the combined operation, but has the power to operate the dump and elevator separately. In addition, there is no, unnecessary wear and tear on the parts .dueto useless operation and running, asthe elevator and dump may be run separately, as desired.

What I claim is I 1. In combination with a motor, an elevator and a dump, a driving shaft connected to the motor, a shaft for driving the dump,

and means for moving said clutchingmember, saidclutching' member being adapted to connectsaid driven element in operative ref I lation with said driving s'haftfsaid means being also adapted to connect said dump driving shaft in operative relation with said driving shaft, said means being so constructed that when one of said connections is made the other connection cannot be made without breaking said first mentioned connection, and vice versa.
